## Biography

Donald Robert Wilton was born on October 25, 1942 in Lawton, Oklahoma. He received B.S., M.S., and Ph.D. degrees in electrical engineering from the University of Illinois Urbana-Champaign, in 1964, 1966, and 1970, respectively. From 1965 to 1968, he was affiliated with Hughes Aircraft Company, where he worked on phased arrays. He joined the Department of Electrical Engineering at University of Mississippi in 1970. He was a visiting professor at Syracuse University from 1978 to 1979. From 1983 until his retirement in 2012, he has been with University of Houston, where he is a professor of electrical engineering. Wilton is best known for his work in computational electromagnetics: he has introduced the namesake Rao–Wilton–Glisson (RWG) triangular surface basis functions, widely used in method of moments modeling of complex structures, with his doctoral students Sadasiva M. Rao and Allen W. Glisson.
Wilton is a member of Commission B of International Union of Radio Science and is a fellow of the IEEE. In 2015, he received IEEE Electromagnetics Award "for fundamental contributions to integral equation methods in computational electromagnetics." In 2021, He was elected to the National Academy of Engineering for "contributions to computational electromagnetics of highly complex structures."
